The most important system software that runs on a computer is the operating system.Every general-purpose computer must have an operating system to run other programs.Operating systems perfrom basic tasks ,such as recognizing input from the keyboard,sending output to the display screen,keeping trach（错别字吧） of files and directories on the disk, and controlling peripheral devices such an disk drives and printers.一台计算机上运行的最重要的系统软件是操作系统，每个通用计算机必须有一个操作系统来运行其他程序。操作系统之行基本任务，例如识别键盘输入的东西，将信息输出到显示画面，保存磁盘上文件和目录，并控制外围设备，如一个磁盘驱动器和打印机。

A computer network is a communications system connecting two or more computer that work together to exchange information and share resources .We know some network devices like hub,modem and router etc.The word modem is short for "modulator—demodulator"Modem convert digital signals to analog signals and vice versa.计算机网络是连接两个或多个计算机的通讯系统，可以和交换信息和共享资源一起运行。我们知道像集线器，调制解调器和路由器等一些网络设备，modem（调制解调器）全称是"modulator—demodulator"（“调制器-解调器”）。调制解调器将数字信号转换为模拟信号，反之亦然。

Network architecture describes how the network is arrange and how the resources are coordinated and shared. A network can be arranged or configured in several diffirent （错别字）ways.This arrangement is called the network's topology .The four principal network topologies are star bus ring and hierarchical. 网络架构描述了网络是如何安排以及资源如何被协调和共享的,一个网络可以以多种当时被安排或配置。这种安排被称为网络的拓扑结构。这四个主要的网络拓扑结构是星形总线环和分等级的。
